DOOR STOPPING AND HOLDING DEVICE File'd Nov. 4, 1940 Patented Aug. 17, 1943 UNITED STATES PATENT OFFICE 2,327,298 DOOR STOPPING AND HOLDDTG DEVICE George G. Wycko-fl, Chicago, m. Application November 4, 1940, Serial No. 364,114 8 Claims. (Cl. 292-78) This invention relates to a door stopping and holding device used in connection with a swinging door that is usually provided with a stop at the base-board or at its lower end to limit its opening movement.

An object of the invention is to provide a simple, sturdy and inexpensive device of thistype which will serve as a stop to limit the opening movement of the door and will at the same time hold the door in open position. The device is small and compact, and projects a minimum distance from the door so as to eliminate any interference with the use of the space adjacent the door opening,

A further object of the invention is to provide an improved construction in which the opening movement of the door is checked before the door is brought to a stop and is held in its open position against drafts or slight impulses that often release a door and cause it to close.

More specifically the invention is directed to a construction employing a swinging member pivotally mounted preferably at the lower end of the door and is adapted to swing outwardly to align with and engage a projection or rise on the fioor whereby to ride upon such projection and to be forced into a door holding position. In this position, the door will resist a draft or other jarring force that may come against it but will readily release the swinging member when the door is intentionally pulled closed. The structure comprises few rigidly constructed parts devoid of springs or other members that require attention and repair at intervals.

Other objects and advantages of the invention will be apparent in the following detail description taken in connection with the accompanying drawing which forms a part hereof.

In the drawing: 4

Fig. 2 is an end view of the door and device shown in Fig. 1, with a portion in section to illustrate the manner of stopping and holding the door in openposition;

Fig. 5 is a sectional view taken along line 5-5 of Fig. 3;

Fig. 7 is a detail sectional view of the lower end of the swinging member to illustrate another variant embodiment of the invention; and

Fig. 8 illustrates the manner of mounting the projection on the floor where a carpet covers the floor.

The device illustrated in the drawing as showing a preferred embodiment of the invention comprises a vertically swinging member 5 pivotally mounted adjacent the lower edge 6 of door 1 by any suitable attaching means which may be a U-shaped bracket 8 secured to a face of the door by screws l0. Bracket 8 preferably has its cross leg ll positioned against the door and screws l0 enter openings in 'the same so that they may be forced into the door to hold this bracket securely thereagainst, Swinging member 5 is pivotally mounted to move between opposed legs M of this bracket 8. The pivotal mounting may consist of a pin l3 passing through the upper part of swinging member 5 as well as opposed legs l2, so that the ends may be headed, as illustrated M, upon the outside face of legs 12.

Swinging member 5 may comprise a tube or like hollow member l5 that extends downwardly to the floor when suspended in a vertical position from pivot l3. The lower face Hiof tube I5 is adapted to clear the floor and be spaced thereabove a predetermined distance, preferably a distance permitting it to swing outwardly,. as shown in Figs. 1 and 2, without touching the floor. Normally, swinging member 5 is held in this position by resting against a pair of detents ll formed in side walls J2. When door 7 is moved to open position, lower end l6 of swinging member 5 is adapted to engage and ride upon a projection or rise on the floor, such as the head W of a screw 20. The manner in which lower end it will engage screw head I9 is illustrated in Fig. 2. The force of the opening movement will cause swinging member 5' forcibly to bear against detents ll. The pressure will result in a spreading of these detents to permit member 5 to snap therebeyond in the position shown in Figs. 4 and 5. Hence, these detents'l'l initially act as a check to restrain the force of the opening movement of door 7 and aid to arrest the door in its open position. Detents I! are spaced, with respect to cross'leg H of bracket 8, to provide a snug fit for member 5 between the same and this cross leg II when latched in its vertical door holding position. The door will be held as to interfere with the use of the floor.

2 tightly in this position and rattling of the door by drafts will be prevented.

The lower end I6 of swinging member 5 is preferably adjustably mounted so as to permit a predetermined spacing thereof above the floor. This adjustment is desirable because it eliminates making the mounting of the device upon the door critical with respect to its height above the floor and further eliminates difiiculties in its operation as the result of variations in the level of the floor. To this end, tube l5 of member 5 is adjustably carried with respect to an upper part 2 l which receives pivot l3. As illustrated in the drawing, tube I5 is internally threaded at its upper end to receive this upper part 2|, the latter being in the instant disclosure in the form of a threaded bolt and a lock washer 22. In the event the lower end l6 extends too far from the floor, member 5 might be pulled free of screw head 19 without kicking past detents I! to its inclined position shown in Figs. 1 and 2. Upon a subsequent opening movement of the door, the forward edge of lower end [6 will strike against the bolt head 19 instead of clearing the same,

as illustrated in Fig. 2. Member 5 will then be unable to engage over head I9 to act as a stop and hold the door in op n position. It is, therefore, desirable to have an adjustment that, can be conveniently made by anyone after the device is mounted upon the door. Any form of adjustment may be provided, and consequently, I do not wish to be limited to the exact structure shown.

Moreover, the projection or rise upon the floor adapted to cooperate with swinging member 5 may take any formthat will produce the desired results. In the event the floor is carpeted, bolt 20 may be provided with a washer or fiat plate disposed below head l9 so that carpet 26 may be held firmly under head I!) and not be disturbed by the use of this bolt.

A variant embodiment of the invention is illustrated in Fig. 6. Member 5 is provided with a solid rubber tip 21 adapted to engage and ride upon a rise 28 secured to the floor. Rise 28 forces swinging member 5 to its vertical position, as shown, so that it will be latched in this position by being forced to the right beyond detents H. The frictional engagement between rise 28 and tip 21 can be made suflicient to hold the door in open position, as well as arresting its open movement to act as a stop.

In this connection, it is pointed out that the invention does not limit the construction of tube 15 to a hollow structure, as illustrated in Figs. 2and 3. Tube l5 may be solid with its lower end provided with a recess 29 of sufficient depth to permit bolt head l9 to be received therein.

From the foregoing description, it will be apparent that a novel type of door stopping and holding device i disclosed that is simple, sturdy and inexpensive to construct. The parts are small and compactly arranged. If desirable, a cover 30 may be provided to extend over and upon bracket 8, Legs l2 are preferably slanted along their front edge so that this front edge may be approximately parallel to the position assumed by swinging member 5 when it is free from the floor projection l9. Cover 30 gives the device a somewhat streamline hooded appearance. It substantially encloses swinging member 5, which is the only movable part of my device. It will be understood that this floor projection ill need not be so large As a as illustrated in Figs. 1 and 2. I

matter of fact, the extent of the projection from the floor is so inconsequential that this area about the door may be used without danger of tripping.

Without further elaboration, the foregoing will so fully explain the gist of my invention that others may, by applying current knowledge, readily adapt the same for use under varying conditions of service, without eliminating certain features, which may properly be said to constitute the essential items of novelty involved, which items are intended to be defined and secured to me by the following claims.
